"Remember I told you my coach (Glen Mills) said 'stop worrying about your start, the best of your race is at the end, that's where you rule'. So I stopped worrying about the start and I executed, so it worked."

Bolt paid tribute to training partner Blake, predicting the 2016 Rio de Janeiro Olympics may be the platform for his countryman to make his mark on track and field's greatest stage.

"He (Blake) works harder than me, but I knew what I needed to do and I have great talent," he said.

"He will do better next time because he was a little bit stressed this time."

Blake, who defeated Bolt at the Jamaican trials in Kingston in late June, was not disappointed to finish runner-up in London.

"He is the fastest man in the world and I've got a silver medal," he said.

"What more can I ask for?"

Gatlin only returned from a four-year doping suspension in 2010 and described his satisfaction in making it back to the Olympic arena.

"It feels great to be back after eight years," he said.

"Simply just to come back and use my God-given talent. I went out there and I did the best I could do."
